Question

(5,07 :1/20 -23,4 :13/50) *1/4+0,074*1/2

Answer 1

1.5,07 :1/20 -23,4 :13/50=11.4
2.11.4*1/4=2.85
3.0.074*1/2=0.037
4.2.85+0,037=2,887

Answer 2

To simplify the given expression step by step, follow these calculations:

1. First, simplify the fractions: (5.07 * 1/20 - 23.4 * 13/50) * 1/4 + 0.074 * 1/2

   = (0.2535 - 3.834) * 1/4 + 0.037

2. Now, perform the subtraction inside the parentheses: = (-3.5805) * 1/4 + 0.037

3. Next, multiply -3.5805 by 1/4: = -0.895125 + 0.037

4. Finally, add the two results together: = -0.895125 + 0.037 ≈ -0.858125

So, the simplified value of the expression is approximately -0.858125.
